Violet ★★★★★

Fits my old South Bend chuck perfectly and the square drive is machined cleanly so it doesn’t slip. Feels solid in the hand when tightening the jaws.

Scarlett ★★★★★

The 11mm square drive fits my chuck perfectly, no wobble at all. Turning the key feels solid and well-machined—it’s a simple tool, but it does exactly what it should.

Alexander V. ★★★★★

My old key kept slipping on the chuck, but this 11 mm square fits the 7/16 inch slot perfectly and turns with solid, positive engagement. It’s a simple, exact replacement that does the job without any fuss.
